INVENTOR ATTORNEY Patented Oct. 29, 1929 PETER LALANNE AND HARRY M.annsrnon'e, on sna'rrrn, 'WASHINGTON, ASSIGNOR-S TO WILLIAM C. BRANDT,OF SEATTLE WASHINGTON WIRE enrrrnn v Application filed May 31,

machines and the object of our invention is to provide a wire grippingdevice of simple and eificient construction that may be installed on awell known standard type of wire tieing machine to make it possible touse long lengths of wire, as from a roll or a reel of wire, by cuttingthe amount required for tieing, off of the end of the wire each time atie is made, instead of using short lengths of wire already cut tosubstantially the right length as is ordinarily done at the presenttime.

Other objects are to provide a wire gripping device of this nature thatmay be installed on a standard wire tieing machine with very littlealteration of the parts of said machine, and that will make it possibleto use a cheaper wire for tieing purposes and to economize on the amountof wire that is used.

Other and more specific objects will be apparent from the followingdescription taken in connection with the accompanyingdrawings.

' plan view of a wire tieing machine of well known standard constructionhaving a wire gripping device constructed in accordance with myinvention installed thereon.

Fig. 2 is a detached plan view of the wire gripping device.

Fig. 3 is an edge view of the same.

Fig. 4 is an end view of the wire gripping device taken on broken line44 of Fig. 2.

Referring to the drawings, throughout which like reference numeralsdesignate like parts, I show a wire gripping device embody ing a baseframe 5 adapted to be secured to an arm 6 and provided with two upwardlyextending lugs 7 and 8 that form bearings for a shaft 9. Alower,non-movable, wire gripping jaw 10 having teeth 11 is fixed to the outerend of the frame member 5 and an upper movable gripping jaw 12 havingteeth 13 is secured to the end of the shaft 9 and adapted to be movedtoward and away from the jaw 10 by oscillation of said shaft. A spring14 on the shaft 9 is arranged so as to urge the movable jaw 12 down ontothe fixed 192s. Serial no- 281,681.

jaw 10.' A lever 15 is securedonlthe i or rear end of. the shaft 9 andserves as a means by which the tensionof thes'pri'ng 14 may be overcomeand the 'movable jaw member 12 raised to release a wire. Anut16,1"etains the lever 15 in place. A member 17 projects inwardly fromthe arm 6 and a roller 18- is rotatably mounted in the inner end of saidmember 17! The arm 6 may be apart of the wire tieing machine and theframe '5 may be detachably secured thereto by screws 19. This makes aneasy means ofattaching the wire gripper to the tieingmachine.

w The inner or rear end of the arm 6 is connectedby a pivot 20 with theframe 21 of, a wire tieing machine of standard construction, notspecifically described herein. A spring 22 on the wire tieing machine isconnected with a slu g 23 onthe arm 6 and urges the wire gripperinwardly toward the machine. An operating lever 24 on the wire tieingmachine is arranged to come downon the top of the end of the lever 15when the machine is in the inoperative position to hold the wiregripping jaws 10 and 12 apart or Open Suitable cam means, indicatedgenerallyat 25 is provided for direct or indirect contact with theroller 18 to govern the movement of the gripper toward and away from themachine.

In the operation of this wire gripper the wire is drawn around anarticle, as a box that is to be bound with wire, and through the tieingmachine and an end of-the wire is then placed between the jaws 10 and12. As soon as the operating handle 24 is raised, the lever v 15 isreleased and the spring l4ijspermitted V to close the top jaw 12 downonto thewire so that, when the gripping device is afterwards movedoutwardly away from the'wire tieing machine in tightening the wirearound a package the pull of the wire'in the direction indicated'by thearrow in Fig. 4-will-cause the awsto grip the wire more tightly. Afterthe tieing of the package the operating lever handle 24 will be returnedto the inoperative position shown in Fig. 1 causing it to en'- gage withthe releasing lever 15, raise the jaw 12 and release the end of thewire.

By the use of this gripper in combination with a wire tieing machine ofthis nature we a movable wire gripping jaw secured to the are enabled touse wire from a roll or reel which is much cheaper than bundled wire cutto special lengths and we are further able to effect a substantialsaving in the amount of wireused. Where bundled wire is used it isobvious that different lengths will be necessary for diflerent sizepackages but where wirefrom a roll is used the difference in'size ofpackage is'automatically taken I care of. v

The foregoing description and accompanying drawings clearly disclose apreferred embodiment of our invention but it will be understood thatthis disclosure is merely illustrative and that such changes may heresorted to as are fairly within the scope and spirit of the followingclaims.

What we claim is 1. A wire gripping device of the class describedembodying a frame, an oscillatory shaft supported on the frame, a fixedand a movable gripping jaw supported respectively on the frameand onsaid shaft, a spring urging the movable jaw toward thefixed jaw and areleasing lever on the shaft for moving the movable jaw into releasedposition.

2. A wire gripping device of the class described, embodving a frame, ashaft mounted for oscillation on the frame, a fixed wire gripping jaw onthe outer end of the frame,

outer end of the shaft and arranged to cooperate with said fixed jaw togrip'a wire, a

spring on the shaft yieldingly urging the movable jaw toward the fixedjaw and a release lever on the rear end of said shaft for moving saidmovable jaw away from said fixed jaw.

3. The combination with a wire tieing machine having an operating lever,of a wire gripping device, embodying a relatively long rame pivotallysecured at one end to said wire tieing machine, a shaft mounted foroscillation on the frame, a fixed wire gripping jaw on the outer end ofthe frame, a movable wire gripping jawsecured to the outer end of theshaft and arranged to cooperate with said fixed jaw to grip a wire, aspring on the shaft yieldingly urging the movable jaw toward the fixedjaw, a release lever on the rear end of said shaft positioned so as tobe engaged by the operating lever on the machine for releasing said wiregripping jaws when said operating lever is in an inoperative positionand cam roller means projecting sidewise from said frame into said wiretiein g machine,

n witness whereof, we hereunto subscribe our names this 25th day of May,A. D.
